Iphone 5 Unlocked with tmobile sim question.
Sorry I'm not used to using forums. I wanted to go back to using an iphone after using the nexus 4 and nokia lumia 810. I originally had and iphone 4 with Verizon but the service was horrible at my job and went to tmobile. now that they don't have contracts I was more interested if its worth buying the iphone from Apple unlocked with a tmobile sim. The reason for this is because I want the phone to be automatically unlocked and not having to deal with tmobile if I did the payment plan and got it through them with relying on them to give me the unlock code. I noticed Apple sells the iphone 5 with a T-Mobile Sim, but is it T-Mobile locked? (sorry for the long read)
-Any help is appreciated. Also, on a side note if I don't get the iphone 5, would a unlocked sprint 4S work on T-Mobile?
